Then I remembered… oh yeah, everything is bigger in America (especially in Texas)!
But I do agree with you. We live in a 4 bedroom detached house approx 120 sqm and this is plenty of space for a family. In fact, it's above average space out of all the families I know...
So they don't really need more than a studio anyway. Nor would they clean/maintain it anyway.
Yeah, 1400 as "small" is very US oriented :). But having grown up in the US, I really miss the space of the houses.
